Blender 2.8 Command Line: Errors on running script
Thankyou @RobertGützkow for your help!

The solution was true that I needed to have a python-specific file (outside of blender) that I could run.

To do this I 

1) created a new Text.txt file
2) named it the same name as my script (optional)
3) copied and pasted the code into the text.txt file
4) rename the text.txt --> text.py
5) add the text.py file path to the code.

Here's what mine looked like :
(with the command prompt pointed at blender)

C:\Program Files\Blender Foundation\Blender>

blender H:\Blender3d\ScriptingPractice\scriptingpractice.blend -P H:\Blender3d\ScriptingPractice\genererate_tears.py
